VINCENT TORNABENE,

or oHrCAGo, ILLINoIsJ y :DEMOUNTABLE RIM on THE'LIKE.

Application filed December 27,1919. Serial No. 347,723. r

To all 107mm t may concern.' y y .y j

Be itlrnoWn that I, VINCENT TORNABENE, a citizen of the United Statea-residing at Chicago,y in thecounty of Cookand State oflllinoisyhave invented certain new and useful Improvements in -Dernountable Rims `or the lilre .of which the following is a de# scription. Y My invention belongs to that general class 10 of devices knovvnas demountable rims and relates ymore particularly to -an improved construction or device for detachably securfing'vtherim and infiated tire on. the felly. rlhe invention has among its objects the production of a device of the kind described,

Withoutpnuts or bolts,k that is simple, convenient, durable, eflicient, safe andsatisfactory for use, Wherever' found applicable. .It :has ramong its further objects the production of a deviceof the kind described, which will secure the demountable rim on the wheelwithout rnecessitating the use of and necessary tightening of nuts ordinarily used or removal of the same when the rim is removed. Many other l objects .and advantages of the construction herein shown and described will be obvious from 'the disclosureherein made. y

To this end my invention consists'of the novel construction, arrangement and com binationr of `parts herein shown and de-l scribed and more particularly pointed g out in the claims. c j

. vReferring to thedrawings. 1 represents the Wheelfelly and 2 the spokes. it being -nnderstood .that the same may be made of anyfsuitable'k material and be of the desired size and shape. The demountable rim-.3

shown is provided with the edge flanges Il arranged to engage the beads on the casing v5',Within which is arrangedtheinner tube 6. It maybe mentioned that it is immaterial in sofar as the present invention is concerned hon the flange portions dare conf` .Y

"structed, this ordinarily depending` upon the style or type of tire, as,` lfor example,v

straightside,clincher, etc. ,Y l

i Arranged on the felly A1 is a rim part V'l' which is preferably formed With a flange -S on the inner side. The rim part`7 is of such size-or Width inthe preferred construction that the edge 9 extends tothe opposite side of-the felly from the flange 8.. Part if is` also provided with the desired number' of projections `l() or the vequivalent which are arranged to engagewith the centervof the j rim 3, as mostl clearly shown inI Figuresl and 2. It is immaterialhhowpartiis sevcured in thefelly. Arranged to cooperate with the rim part 7 is a rim partr llwvhiCh' is 'preferably ianged as at 12 on ythe outer edge,r the sameA corresponding' with the flange 8 on the other rim part, the rim being of a size to Slipcover part 7 and ofl a 'Width .y so that the edge lilextends to a'point sub` stantially adjacent theA flange 8. The rim part 11A isprovided With `*cut-out portions 14 and, 15.A rlhe cut-out portions lll provide Aclearance `for the projections 10. Arranged on one rim part, as shown on the rim part 7, are pins or lugslG, orthe equlvalent, of

,the desired sizeand shape7 which are arranged to engage in the slots 18` formed in .l the other rim part7 as shown on part 11, and

adjacent vthe cut-outportions 15.l It will .bevnotedthatthe one edge 17 is substantially cam shaped, the purpose ofwhich will be inorefully explained hereafter. j

The rim part 11 as sliownis provided with one or more holes or openings 19 and the felly 1 is'providedwvith one or more llocking members or bolts .2O arranged to engage thereat,1(onlyone bolt 20 is shown).

Locking member or bolt ZOis shown prodivided with a collar 21 or flan-ge, and exl` `tends through a plate 22 secured on the felly, the same being maintained normally inthe position shown in Figure l by a spring23 bearing against the flange Ql and plate 22. The locking member 2O is shown with an end 24 conveniently formed toi' grasping and withdrawing the locking member lwhen required. As most clearly shown in Figures 4c, 5 and 6, the member is provided with a lug 25 and plate 22 with the cut-out or notch 25,so that when the bolt 20 is turned to register the lug 26 with the notch 25, the bolt may lbe withdrawn as shown in Figure 5 and if given a slight turn will be maintained inits Withdrawnposition. lf desired one or more lugs 28 may be arranged on the rim part Vll vor'convenience fin-'manipulating the rim part l1. r`A plate 21' )and sleeve 22 may be employed ii' idesired.

fl-*he operationof the device may be briefly described 'as follows: Assuming that rim 3 ,land the-tire carried thereby, as well as rim `part fil, are `removed 'from the wheel and bolt 2Ov withdrawn. 'To apply the rim 3 and-partscarried thereby to tliewheel, rim 3 is seated substantially Aas shown in lFigure 2. VRimV part l1 is then positioned and pushed into place/between the rimparts 3 and 7, it alsoat'the same time being-given a slightfturning movement. That isl to say one or A-the other of rim parts 7 and l1 yis fturned'relativelythe other, so that the pins to withdraw "from operative position.

16 engagein notches 18. Turning the parts also drawsthe part 11 inwardlyjasthe pins engage T'aces 17. `-Lockingbolt v20 is 4then ltuiuied and permitted to vtake its normal 'locking position as shown vin Figure t, preventing relative turning vor sliding movements oit/the rim parts. It necessary rim part ll may be slightly tapped with a ham-l 4mer or thelike,`the llugs 28,l ot which there #may be any number, affording convenient Ifaces to be engagedto turn-the rim part.

To reniovegthe rim '3 the operations just delt may be mentioned tace, as indicated in" the dotted line X, turning the rim part l1 back relative to part 7, it will, also have a tendency to cause part' 11 It will be seen from thepreceding that itis possi-ble fto remove one rimand replace 4another lone onthe wheel withoutthe use of wrenches, as there are no nuts, bolts or ,the like y-to be removed, nor -afplurality of loose parts to become mislaid orlost. "With- .drawing-the lockingbolt 20, and it maybe mentionedthat there may be any number of bolts 20 provided, releases the entire mechanism. However it will be noted that there is'practically no sti'aiii on bolt 20 as lthe strain istaken bythe pins'or lugsl.`

'Having thus described my inventiony it 'is obvious that various immaterial modications may be made in the same without departing 'from the spirit ot my invention,

jhence' donot wish to be understood as limiting myseli to the exact construction4.l arrangement, combination of parts or usesy mentioned except as deined by the claims hereunto appended.
